The antimicrobial property is the key feature of active packaging. Biological macromolecules such as tannic and gallic acids are naturally found in plants tea, fruits, berries, grapes. incorporation acid (TA) (GA) biodegradable polymer blend Poly Lactide-Poly (Butylene Adipate-Co-Terephthalate) (PLA-PBAT) was used this study to assess potential TA GA (10 wt%) composite films showed a 65%–66% in...

Poly (lactic acid) (PLA) is an important biodegradable plastic with unique properties. However, its widespread application hindered by low miscibility and suboptimal degradation To overcome these limitations, we investigated the mechanical, thermal, properties of PLA poly (butylene sebacate-co-terephthalate) (PBSeT) blends in presence (ethylene oxide) (PEO). Specifically, this study aimed to id...

Morphological and rheological properties of poly(lactic acid), PLA (semicrystalline amorphous), poly(butylene adipate-co-terephthalate), PBAT, their blends (75 wt%/25 wt%; PLA/PBAT) were investigated in the presence cellulose nanocrystals (CNCs) prepared from solution casting followed by melt mixing. For step, CNCs either incorporated into matrix, dispersed phase, or both. The dispersion distri...

We present a combined macro-scale/micro-scale computational approach to quantify oxygen transport and flow-mediated shear stress to human chondrocytes cultured in three-dimensional scaffolds in a perfusion bioreactor system. A macro-scale model was developed to assess the influence of the bioreactor design and to identify the proper boundary conditions for the micro-scale model. The micro-scale...

The clinical success rate of islet transplantation, namely independence from insulin injections, is limited by factors that lead to graft failure, including inflammation, acute ischemia, phase response, and insufficient vascularization. ischemia vascularization both high levels oxidative stress, which are further aggravated encapsulation, undesirable cell-biomaterial interactions. To identify b...

Monitoring extracellular matrix (ECM) components is one of the key methods used to determine tissue quality in three-dimensional scaffolds for regenerative medicine and clinical purposes. Raman spectroscopy can be used for non-invasive sensing of cellular and ECM biochemistry. We have investigated the use of conventional (confocal and semiconfocal) Raman microspectroscopy and fibre-optic Raman ...

The use of natural antimicrobial additives, such as orange essential oil (OO), can be a promising possibility to increase food shelf life with the aid active packaging. This study aimed develop an packaging using and PBAT - poly (butylene adipate co- terephthalate) store mozzarella cheese produced by fine film extruder 5, 10, 15% OO (w/w). In results, D-limonene was oil’s main constituent activ...
